Please browse and make use of these materials. Each title is one training unit—the total sum of materials for one single class, session or lecture. One unit may be one video of a two-hour lecture. Another may be several files including class handouts, presentation slides, trainer’s notes, and homework.

Members can add their own tags and comments to any unit. Your input and data is greatly appreciated! Success stories and suggestions will help us build this community to better serve you, our future trainers and students.

WiMAX has raised many expectations promising greater range, QoS and roaming capabilities beyond what WiFi can offer. But prices remain significantly higher than solutions based on WiFi modifications and some proprietary technologies. A description of the main features of these three general categories is presented with some examples.

By using external antennas and modifying the firmware, very low cost, long distance WiFi links can be built. High gain antennas require careful alignment, that most be done using signla generators and spectrum analyzers. A low cost version of these is presented.

Consider gender perspective in order to achieve fairness and equality of opportunities between women and men in the use andappropriation of technology, in particular for ICT and community networks. Contribution of ICTs to the development of communities.

Define basic concepts of sustainability. Provide a guide to identify factors that may be critical for the sustainability of community wireless networks. Analise examples of projects that have used Wi-Fi technology in their networks.

In this note, detailed design as well as step by step on how to make a wokbolic & bazooka antenna for 3G will be described. PVC tubing & aluminium tape is used to make a low cost wokbolic & bazooka antenna.
